I got rejected by 3/3 programs (biology, likely marine focus). I spent the last week in a haze thinking that all the effort I've put into 16 years of schooling was not worth it and I wasted my youth, because the only job I got was the one I had in high school at a dog kennel. After my allotted sulking period, I found making new plans makes it feel A LOT better. I found a reach POI (he's studying sharks about an hour from my hometown... awesome!) and asked if I could volunteer in his lab for free on my days off. I'm signing up to get SCUBA certified. I'm signing up far in advance for subject GRE's and going to enjoy learning the stuff I like at my own pace. I'm also hoping going over every sub-subject in the field will help me figure out my exact interest.
Find fun ways to bulk up your application for next year and find your direction. I swear, I am a very negative, pessimistic person, but right now I actually feel GOOD about all my rejections! Minus the living at home part... that still makes me feel like a hobo...
Also, I emailed my schools and asked what else I could do to improve my application/ what my weakness were. I got an email today from one POI saying he wanted to take me but didn't get his grant, and that he's reapplying for it and wants to meet with me over the summer. He's not in my newly focused field of interest but MAJOR moral boost!
